Setting up a Windows computer to share files with Mac
users
You can set up a Windows computer to share files with other users
on your network, including Mac users.
To let users connect to a Windows computer from a Mac computer, you
need to share a folder on the Windows computer.
To connect to the Windows computer, users need the network address
for the computer, the workgroup name, and the user name and
password for the shared folder:
To see the computers workgroup name and computer name, open the
System control panel, then click the Computer Name tab.
To see the names of user accounts available on the computer, open
the User and Groups control panel.
To see the IP address and DNS name of a Windows XP computer, look
in the Details pane of the Explorer. You may need to open the
Network Connection control panel and select the connection youre
using. The information appears in the Explorer Bar.
